      Pirani 1.00e-3 mbar IE514 2.83e-7 mbar

     The Leybold IE514 gauge currently in use is the CARME unit ( serial # 1054 ). The calibration data can be found at https://elog.ph.ed.ac.uk/CARME/56

10.10 Leak tester attached to backing line

      Valves to leak tester and turbo (connection to Edwards scroll pump in between) closed.

      Stop Edwards scroll pump with magnetic valve 'red' button - magnetic valves closes and Edwards scroll pump is switched off.

      Open valves to leak tester and then (slowly) turbo.

      Wait for leak tester to settle in e-12 mbar.l/s range. Leak tester pressure 3.6e-3 mbar. IE514 2.69e-7 mbar.

      Leak testing.
      Downstream DN100 flanges from CARME to dipole OK
      Lower NEG power connector feedhtrough (downstream chamber) OK
      Left hand side (looking downstream) bellows OK

      c. few e-9 mbar.l/s leak bottom left (lookimg downstream) of COF600 wire seal

      Additional torque to M16 bolts bottom left - c. 10 bolts -> 220Nm+

      c. 0.1-0.3e-11 mbar.l/s

      Further checks around circumference of COF600 seal reveal some small leaks c. e-11-12 mbar.l/s.? However background rate
      in leak tester too high for sensitive test - will await recovery to resume checking.

15.40 c. few e-9 mbar.l/s leak around magnetic valve - probably not an issue in terms of backing performance but may interfere with/confuse leak testing

16.05 Pirani 9.8e-4 mbar IE514 1.74e-7 mbar
      Leak tester 1.2e-9 mbar.l/s

Will leave CARME pumping with leak tester on roughing line and see whether leak rate recovers. If so, will continue leak tests tomorrow.

10.33 Pirani 1.00e-3 mbar IE514 8.55e-8 mbar
      Leak tester c. 4e-10 mbar.l/s (leak tester connected to CARME roughing line)

10.55 Leak tester remains at few e-10 mbar.l/s - we do not understand why
      With leak tester in differential mode the highest reading around the COF600 seal is c. 3.5e-12 mbar.l/s
      Following checks elsewhere on the chamber we observe c. 6e-12 mbar.l/s which presumably reflects accumulation of He around the chamber 

      Dispersing He with compressed air reduces diff mode reading to c. 2e-12 mbar.l/s

2x ( of 4x ) SAES D-2000 neg power cables were broken - forward-shell detached (unscrewed ) from back-shell remaining attached to D-2000 neg power connector. 
Re-assembly is straightforward but it is unclear how the 6x female sockets are aligned with the connector keys of the forward-shell (attachments 10-11 cf. attachment 9).
Until this is understood these 2x SAES D-2000 neg power cables should not be used.

      The thermocouples on the 3x groups of heater elements have been detached from direct contact with the heating element and now float abpove the heating element by 2-
3cm - see attachments 1 & 2

      The vacuum group IE514 and Ametek RGA are still attached to CARME - see attachment 3. Have requested vacuum group remove them.

      The 'air side' of the Be window on the interaction chamber is under vacuum provided by small Agilent scroll pump.

the CARME interaction and detector chambers yesterday and today.

      The CARME bakeout monitor shows recovery from test yesterday evening. The ELOTECH controller was switched to manual mode for the 3x CARME zones and 5% power selected 
for 45 minutes. CARME TCs increased from mid-20s to high 20s/low 30s over a period of 45 minutes. At the conclusion of the test power was set to 0% for all 3x CARME zones 
and the mode changed from manual to controlled.

10.15 Commence bakeout ramp
      Set all ELOTECH PID temperature controller zones ( channels ) to 50 deg C
      Expect all non-CARME zones to reach temperature set point quickly. There will be a delay for the TCs corresponding to the CARME heaters but the internal CAME TCs 
will respond more slowly- will observe response of CARME TCs over time.

15.20 Whilst all of the ELOTECH temperature controller TCs are at their current set point ( 100 deg C ), the CARME TCs are not yet at equilibrium. Plan to leave system 
in current state until tomorrow morning. Assuming CARME is at equilibrium will then increment ELOTECH temperature controller TC set points.

no data observed from aida06 & aida11
 aida11 known to be disconnected from adaptor PCB

aida15 asic #2 may be faulty

aida01, aida05, aida12 - data suggest FEE64/adaptor PCB alignment issue ?

aida02, aida03, aida09, aida14 - data suggest adaptor PCB damaged pins ?


aida07 - network config issue ?

aida08 - not completing boot

need to attach sys console to aida07 & aida08 to diagnose problem.
